` ellciaims'. (o1. 293-54) The present invention has to dovwith radiators of the `type used in connection with internal combustion engines.

The purpose ofl the invention is to provide a 1;,1 radiator ofimproved construction which is light,

strong, rigid and durable, vand is quiteinexpensive tol manufacture.

The invention resides particularly in the construction and arrangement of the protective grill is@ with respect to the other structural elements which together constitute the radiator. In the hereinafter described embodiment of the invention this grill is a one-piece sheet metal member which-is provided with a forwardly protruding d front portion and rearwardly extending side portions. The front portion, which may be either V-shaped or bowed in horizontal section, forms a protective guard for the cooling core behind the same, provides a support for the front portion of the'upper tank, and leaves an opening behind the same, accessible from the bottom of the unit, for giving access to the front ofthe core for cleaning. 'Ihe rearwardly extending sides of this one-piece sheet metal member embrace certain of the other parts of the radiator 25 and are secured to the same in such a way as t0 form a well reinforced unit. Y

Other advantages ofthe assembly as hereinafter set forth will appear to those skilled in the art of motor cooling systems.

3 In order that the invention may be readily understood there is set forth in the accompanying drawings and in the specification predicated thereon a preferred embodiment of the same, it being understood that the description and claims based thereon are not to be taken in an unnecessarily restricting sense.

In the drawings Fig. 1 is a front elevation of the assembly; Fig. 2 is a side elevation of the same; 4U Fig. 3 is a horizontal section on the line 3--3 of Fig. 1; f

Fig.y 4 is a vertical section on the line 4--4 of Fig. 1;

Fig. 5 is a detail elevation of the grill;

Fig. 6 is a side elevation of the grill; and

Fig. '7 is a top plan of the grill.

Having particular reference to the drawings, there is shown a radiator at II with an upper water tank I2,.cooling pipes I3 with associated cooling fins I4 together comprising a cooling core, a lower tank |20., an outlet tube I5 leading from the cooling core and a return pipe I6 to the tank I2. Tank I2 has a forward extension I1 which Vcharacteristic assembly of the protective grill overhangs the space in front of the cooling core.y

' sheet metal grill `Iii has vits central portion I 9 `bent to a forwardly convex shape and provided withA apertures to give the grill effect, as indicated atv 20, and has its two sides 2| angularly bent into parallel relationship with the terminal edge of rebentat 22. Intermediate the extent of each of the sideY flanges is a rieb 23 outwardly convex and inwardly concave. The front I9 'of the grill is at the top inwardly bent to form narrow horizontal flanges 24 while the rside flanges 2| w extend upwardly beyond the front I9 as flanges 25; in 4a common plane with the sides, n

The upper tank I2 has impressed thereon at each vside beads 26 which are outwardly convex and inwardly concave and adapted vto be telescopically associated with the beads 23 of the grill side flanges 2l, thus serving to positionand retain the upper tank and the side flanges of the grill in relative position when the grill is disposed with its flanges 24 beneath and in sup- 20 porting relationship to the forward extension I1 of the upper tank with its side flanges 2I disposed at the sides'of and forming a housing for the cooling core.` VIn this position the flanges 24 are secured as by 'spot-welding or soldering or any 2- other approved manner to the lower edge of the tank extension Il while the flanges 24 are likewise spot-welded, soldered or otherwise rigidly aihxed to the sides of the tank. Embracing the lower ends of the assembly, extending the full 30 width thereof,'is a band or strap 21 having its upturned-edges 28 secured as by spot-Welding or otherwise. This band 21 has depending therefrom screw studs 29 by means of which the assen'iblyY is secured to the chassis. n Y

It will be observed that the forming of the grill I8 as forwardly convex, curved or V-shaped, not only enables the capacity of the tank I2 to be increased to the extension of the overhanging forward extension Il but also provides a lower opening at 30 which gives access to the space between the grill and the cooling core for cleaning the latter of accumulated foreign matter;

Thus it will be seen that by reason of the with the tank and the cooling core is attained an refficient cooperative relationship precluding vibration, loosening of the elements inuse, and increase in the tank capacity, easy cleaning of the cooling core and, with all, a pleasing'appear- 50 ance'as an entirety,

I claim v 1. In radiator construction, the combination with top and bottom tanks and circulating core elements, of means for rigidly connecting the 55 tanks comprising a sheet metal stamping of ygenerally U-shaped horizontal section, the sides of which stamping are secured to the sides of botli tanks and the front of which is disposed in forwardly spaced relation to the core elements.

2. In radiator construction, the combination with top and bottom tanks and circulating core elements, of means for rigidly connecting and supporting the tanks comprising a one-piece sheet metal stamping of generally U-shaped horizontal section, the sides of which stamping are PO- sitioned against and secured to the sides of both tanks and the iront of which is perforated as a grill and disposed in forwardly spaced relation to the core elements.

3. In radiator construction, the combination with top and bottom tanks and circulating core elements, of means for rigidly connecting the tankscomprising a sheet metal stamping of generally U-shaped horizontal section, the sides of which stamping aresecured to the sides of both tanks and the front of Which is disposed in forwardly spaced relation to the core elements and is secured to the front of the upper tank.

4. In radiator construction, the combination with top and bottom tanks and circulating core elements, of means for rigidly connecting and supporting the tanks comprising a one-piece sheet metal stamping of generally U-shaped'horizontal section, the sides of which stamping are secured to the sides of both tanks and the front of which is perforated as a grill and disposed in forwardly spaced relation to the core elements, the front of said stamping being secured to the under side of the frontof the upper tank in vertical supporting relation.

5. In radiator construction, the combination with top and bottom tanks and circulating core elements, of means for rigidly connecting the tanks comprising a sheet metal stamping of generally U-shaped horizontalsection, the sides of which stamping are secured to the sides of both tanks and the front of which is disposed in forwardly spaced relation to the core elements, the top of the front of said stamping being rearwardly iianged and underlying the under side of the front of the upper tank in Vertical supporting relation.

6. In radiator construction, the combination with top and bottom tanks and circulating core elements, Yof means for rigidly connecting and l supporting the tanks comprising a one-piece sheet metal stamping of generally U-shaped horizontal section, the sides of which stamping are Vsecured to the sides of both tanks and the front of `which is perforated as a grill and disposed in forwardlyV spaced relation to the core elements, the front of said stamping being of V-shaped horizontal section, With the center of the same farthest removed from the core elements, `and the top of the front of said stamping being rearwardly flanged and underlying the under side of the front of the upper tank in vertical supporting relation.
